The. invention relates to improvements in' smoke washing apparatus applicable to any of the'known types of chimney structure, andpartlcularly serviceable asa ,means of entirely -elim-t 6 inating soot, ashes, debris, and other objectionable particles from, the smoke emanating from chimney stacks and other exhaust ducts ofa like nature. n Y

rIhe invention comprises supporting means at l' and upon thev exhaustl end of `the chimney or otherl like structure and of the attachment thereto of a trough or water reservoir having mounted thereon means supporting an accumulator hood or dome carrying .a suitable baille means ar- 155 ranged to pocket an amount of the gasesemanating from the chimney to form a cushion or buffet body for the smoke, gases,etc., passingtherefrom, and upon which cushion said smoke, gases, ietc. impinge and are deected through a water cur- -i tain or screen formed bya water supply 'disposed in said dome, smoke and gases and precipitating deleterious substances therefrom, to the trough or reclamation means whence itis returned through suitany point of deposit, permitting only the substantially clarified and purified vaporstoemit from the stack. f f

-An objectof the invention residesin thesuperimposing upon rthe emitting end of achimney or;

' stack of a specially formed deiiector hoodpro-y vided with ,a baille an amount of gas wall'arranged to accumulate to act as a bufferv cushion against whichthe smoke contacts and-fromA which the smoke and gases are deflected through the water curtain, thoroughly washing said smoke and precipitating all solids tothe reclamation trough whence same maybe carriedgofl through suitable gravity exhaust means, the action of the smoke-and gases passing from such chimney or stack functioning-as a draft or vacuum head for'the generatorunit.. In the following there is describeddonem-I bodiment of the invention, thefeatures thereofA being more clearly dened "hereinafterin Vthe 4:5c1aims..v

A device of the character described comprising an inverted conically shaped wall mounted to embrace the outlet of a smoke stack and forming a sludge receiving chamber, a hood mounted in spaced relation above said outlet forming a vvent between the edgesof the hood and said wall, an annular upright baille sleeve mounted in said hood, a water head disposed around the outer wall of said bale sleeve adapted to project a water curtain into said chamber across the vent between said hood andwall, a

plurality of nipples mounted in said water head provided with emitting apertures arranged to project said water curtain in an annular unin terrupted curtain circumferentially around the outlet end of said stack to clarify the gases passing through the vent, means for supplying water to said head, and conduit means forconducting 'the sludge from the chamber.
